情态动词（Modals）本身具有一定的词义，不能独立作谓语，必须和动词原形一起构成谓语。情态动词虽然数量不多，但用途广泛。常用的情态动词包括can(could),may(might),will(would),shall(should),must,need,dare,hadbetter,oughtto,usedto等。【beableto的用法】1.beableto后跟动词原形，表示具体的能力，与can的用法相近。Eg:LittleTedisnotabletoanswertheteacher’squestion.2.beableto表示“能力”时，和can的用法相似。但也有区别：(1)beableto有多种时态，如:was/wereableto,will/shallbeableto,have/hasbeenableto等,而can只有两种时态，即can和could。(2)beableto强调通过努力而获得的能力，而can则强调自身已具有的能力。Eg:ShecansingthesonginEnglish.Eg:HewillbeabletosingthissonginEnglishinafewminutes,too.(3)beableto强调一种结果，而can只强调一种可能。

Eg:Luckily,hewasabletoescapefromthebigfireintheend.

Eg:Ifhegothereafewhoursearlier,Icouldsavehim.(4)beableto的否定形式是在be后面直接加not，即benotableto。

Eg:Thekidisnotabletowrite.Eg:But

【haveto的用法】1.haveto意为“不得不，必须”。后跟动词原形。Eg:Ihavetobeoffnow.Thetrainisleavinginanhour.2.haveto与must的区别：(1)must强调说话者的主观意愿；

haveto强调客观上的必要性。

Eg:Thelastbusleft,andJohnhadtowalkhome.

Eg:Imustfinishthepaperbynoon.(2)mustn’t不许，不可以，表示禁止；nothaveto不必。

Eg:Youmustn’tbelatefortheexam.

Eg:Anndoesn’thavetocookforherself.Sheworksatahotelandgetsallhermealsthere.hadbetter后跟动词原形，表示“最好……”，其否定形式是在hadbetter后加not，疑问式是把had和not提前。Eg:Youhadbetternottalkwithstrangers.Eg:Onehadbetterseelifeinitsvariousaspectswhenyoung.Eg:Hadn’tthedoctorbetterseehim医生是不是去看看他比较好？【hadbetter的用法】【dare的用法】1.dare作情态动词时，主要用于否定句、疑问句和条件从句中，一般不用在肯定句中。Eg:HowdareyousayI’munfair2.情态动词dare可以有过去式dared，但也可以直接用dare表示过去式，或后接动词完成式。Eg:Motherdare(d)nottellfathershe'dgivenawayhisoldjacket.3.dare用作实义动词，有时态、人称和数的变化。所不同的是，作实义动词时，在肯定句中dare后面通常接带to的不定式；在否定句和疑问句中，dare后可接带to或不带to的不定式。Eg:Iwonderhowhedares(to)saysuchthings.Eg:Hedoesnotdare(to)answer.【need的用法】1.need表示“需要”或“必须”，作情态动词时，用于否定句和疑问句中，在肯定句中一般用must,haveto,oughtto或should代替。Eg:Youneedn’tcomesoearly.2.need作为行为动词，可用于肯定句、否定句和疑问句中，其后可接名词、代词、动名词或带to的动词不定式为其宾语。Eg:Youneedtopracticereadingaloudeveryday.

注意对need问句的回答:—NeedIfinishtheworktoday—Yes,youmust./No,youneedn’t./No,youdon’thaveto.needn’t对其它情态动词的回答:—ShallItellJohnaboutit—No,youneedn’t/don’thaveto.—Mustwedoitnow—No,youneedn’t/don’thaveto.3.CompletethetipsforgoodtablemannerswiththecorrectformofthemodalsinActivity1.WhilegoingonyourfirsttriptotheUKisexciting,newanddifferentcustomscanalsobeconfusing.Tablemannersarenoexception.Butdon’tworry—herearesometips:•You1._________waituntileveryoneelsehasbeenservedbeforeyoustarteating.•Sometimestherearesomanyknivesandforksthatyou2.__________pickthemupincaseyougetitwrong.Thetrickistostartwiththeonesontheoutside.•Whenyoufinishyourmeal,you3.____________placetheknifeandforktogetheronyourplatewiththehandlesatthefouro’clockposition.Tablemanners,however,candifferindifferentsituations.Forexample,you4.______________________useaknifeandforkwheneatingahamburgerorpizza.Justremember:wheninRome,doastheRomansdo,andyouwill5.__________enjoythelocalcuisine!havetodarenothadbetterneedn’t
